(169, 169+86, 20891)-Net in Base 4 — Upper bound on s

There is no (169, 255, 20892)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3355 399645 690326 782534 180141 771852 634807 032113 225842 537349 955225 622454 168390 186326 985670 144051 280068 384925 796010 654649 656065 054011 193874 289013 883554 207084 > 4²⁵⁵ [i]
